Tunable and Recyclable Piezoelectric Biomaterials via Ion‐Directed Guanine‐Quadruplex Assembly

open access: yesAdvanced Functional Materials, EarlyView.
Guanine‐quadruplex (GQ) assemblies, formed via ion‐mediated self‐assembly of amphiphilic guanine derivatives, are introduced as tunable and recyclable piezoelectric biomaterials. Distinct alkali ions induce unique dipole configurations and piezoelectric outputs, with K⁺ yielding the highest performance.

Local Thermal Conductivity Patterning in Rotating Lattice Crystals of Anisotropic Sb2S3

open access: yesAdvanced Functional Materials, EarlyView.
Microscale control of thermal conductivity in Sb2S3 is demonstrated via laser‐induced rotating lattice crystals. Thermal conductivity imaging reveals marked thermal transport anisotropy, with the c axis featuring amorphous‐like transport, whereas in‐plane directions (a, b) exhibit 3.5x and 1.7x larger thermal conductivity.

Reconfigurable Magnetic Soft Microrobot for Acoustically Triggered Targeted Bacterial Sterilization

open access: yesAdvanced Functional Materials, EarlyView.
Reconfigurable magnetic soft microrobots integrate in situ‐grown piezoelectric zinc oxide nanorods that produce reactive oxygen species upon acoustic excitation. Combining magnetically guided transport with thermally induced planar reconfiguration, the microrobots achieve targeted delivery and enhanced bacterial sterilization through efficient on ...

Comparison of Impulse Response Generation Methods for a Simple Shoebox-Shaped Room

open access: yesAcoustics
Simulated room impulse responses (RIRs) are important tools for studying architectural acoustics. Many methods exist to generate RIRs, each with unique properties that need to be considered when choosing an RIR synthesis technique.

Spectrally Tunable 2D Material‐Based Infrared Photodetectors for Intelligent Optoelectronics

open access: yesAdvanced Functional Materials, EarlyView.
Intelligent optoelectronics through spectral engineering of 2D material‐based infrared photodetectors. Abstract The evolution of intelligent optoelectronic systems is driven by artificial intelligence (AI). However, their practical realization hinges on the ability to dynamically capture and process optical signals across a broad infrared (IR) spectrum.
